Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] Example 1:
[0030] Reference Figure 1-4This is the first embodiment of the present invention, which discloses a plastic support plate for a car child safety seat, including: a support plate body 1, a plurality of weight-reducing holes 102 evenly opened in the middle of the support plate body 1, a plurality of reinforcing ribs 103 fixedly connected to the bottom surface of the support plate body 1, a fixing seat 104 fixedly connected to both sides of one end of the support plate body 1, an ISOFIX buckle 2 fixedly connected to the middle of the fixing seat 104, a storage groove 105 fixedly connected to the bottom of the other end of the support plate body 1, a support component 3 provided in the middle of the storage groove 105, the support component 3 including a sleeve 301, a telescopic rod 303 slidably connected in the middle of the sleeve 301, and a limit component 4 provided on one side of the sleeve 301.
[0031] By setting up the main body 1 of the support plate, the main body 1 of the support plate is integrally molded with plastic material and designed with weight reduction holes 102 and grid-like reinforcing ribs 103. While reducing the overall weight, the cross-distributed longitudinal and transverse reinforcing ribs 103 are used to improve the structural strength, thus solving the problems of the bulkiness of traditional metal support plates and the insufficient strength of plastic support plates.
[0032] Example 2:
[0033] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:
[0034] The main body of the support plate 1 is integrally molded from plastic material. The edge of the main body of the support plate 1 is set as an arc transition surface 101. The edge of the weight reduction hole 102 is rounded. The reinforcing rib 103 includes longitudinal reinforcing ribs and transverse reinforcing ribs. The longitudinal reinforcing ribs and transverse reinforcing ribs are intersected to form a grid structure. The thickness of the main body of the support plate 1 is 3-8mm, and the height of the reinforcing rib 103 is 2-5mm.
[0035] One end of the sleeve 301 is fixedly connected to a rotating shaft 302, which is rotatably connected to the storage groove 105. The bottom end of the telescopic rod 303 is fixedly connected to a support block 304, and the bottom end of the support block 304 is fixedly connected to an anti-slip pad 305.
[0036] The limiting component 4 includes a connecting seat 401, which is fixedly connected to the sleeve 301. A locking pin 402 is fixedly connected to the middle of the connecting seat 401. A buckle 403 is rotatably connected to the surface of the locking pin 402. Several slots 306 are evenly provided on one side of the telescopic rod 303. The slots 306 and the buckles 403 are connected to each other. A torsion spring 404 is sleeved on the surface of the locking pin 402. One end of the torsion spring 404 abuts against the connecting seat 401, and the other end of the torsion spring 404 abuts against the buckle 403.
[0037] The support plate body 1 features an arc-shaped transition surface 101 at its edge, and the weight-reducing holes 102 have rounded corners to prevent children from getting scratched. The anti-slip mat 305 and adjustable support assembly 3 enhance the stability of the seat installation and reduce shaking during driving, thereby greatly improving safety and comfort. With the support assembly 3, the support height can be quickly adjusted to adapt to different vehicle floor gaps by cooperating with the telescopic rod 303 and the limiting assembly 4. During operation, pressing the buckle 403 slides the telescopic rod 303, and the torsion spring 404 automatically resets and locks the slot 306, requiring no tools and achieving convenient and quick operation. With the storage slot 105, the rotating support assembly 3 is embedded in the storage slot 105 when in use, and can be folded and stored away when not in use, saving space and making it easy to carry or store.
[0038] The remaining structure is the same as that in Example 1.
[0039] The workflow of this utility model is as follows:
[0040] First, align and fasten the main body 1 of the support plate with the ISOFIX interface of the rear seat of the car through the ISOFIX buckles 2 on both sides to complete the front-end fixation. Then, pull out the support component 3 from the storage slot 105 and rotate the sleeve 301 to the vertical position. With the setting of the storage slot 105, the rotating support component 3 is embedded in the storage slot 105 when in use, and can be folded and stored without taking up space when not in use, making it easy to carry or store.
[0041] Secondly, press the buckle 403 of the limiting component 4 to release the lock on the slot 306, slide the telescopic rod 303 until the support block 304 contacts the vehicle floor, release the buckle 403, and the torsion spring 404 pushes the buckle 403 to automatically engage with the corresponding slot 306 to complete the height fixation. Through the setting of the support component 3, when in use, the support component 3 cooperates with the limiting component 4 through the telescopic rod 303 to quickly adjust the support height to adapt to the floor gap of different vehicle models. When operating, press the buckle 403 to slide the telescopic rod 303, and the torsion spring 404 will automatically reset and lock the slot 306. No tools are required, thus achieving the effect of convenient and quick operation.
[0042] Finally, when children are riding in the vehicle, the main body of the support plate 1 distributes the force through the reinforcing ribs 103, and the weight-reducing holes 102 reduce the weight while maintaining pressure resistance. The anti-slip mat 305 prevents the support component 3 from shifting when the vehicle is bumpy. Through the design of the main body of the support plate 1, which is integrally molded from plastic material and designed with weight-reducing holes 102 and grid-like reinforcing ribs 103, the overall weight is reduced while the structural strength is improved by using the cross-distributed longitudinal and transverse reinforcing ribs 103. This solves the problems of the bulkiness of traditional metal support plates and the insufficient strength of plastic support plates. The support plate 1 has an arc-shaped transition surface 101 at the edge and rounded corners at the edge of the weight-reducing holes 102 to prevent children from being scratched when they come into contact with it. The anti-slip mat 305 and the adjustable support component 3 enhance the stability of the seat installation and reduce shaking during driving, thereby greatly improving safety and comfort.
[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
